Q. A radioactive material is made at the constant rate of nuclei per second and the material is getting decayed with decay constant . Activity of material after a very long time (if initially there was no radioactive material) is :

Nuclei Report Error

Solution:

After a very long time at equilibrium

Rate of decay =rate of formation
